Rename PPPOE_TODO to PPPOE_SCNAME_SUPPORT because this is the only
feature enclosed by them. Prepare for proper service name and
concentrator name support by moving PPPOE_SCNAME_SUPPORT define to
ppp_opts.h.

Fail to build if PPP_SUPPORT is disabled because PPP_NUM_TIMEOUTS
references defines that are unknown if PPP_SUPPORT == 0. Move
PPP_NUM_TIMEOUTS to PPP_SUPPORT block and set a default value to 0
if PPP_NUM_TIMEOUTS is still not defined at the end of ppp_opts.h.

A deep analysis of simultaneously running timers showed we can use a
slightly smaller value for PPP_NUM_TIMEOUTS_PER_PCB, value which was
arbitrarily chosen to a safe value based on the number of enabled PPP
features. Add the boring and long analysis to the end of our internal
header file and use the result in ppp_opts.h.

Van Jacobson TCP header compression only apply if TCP is enabled,
therefore we need to disable VJ compression if TCP is disabled.
We already have conditions to enforce VJ disabling if IPv4 is disabled
or if PPPoS is disabled, add TCP to those conditions and remove
unecessary VJ_SUPPORT && LWIP_TCP conditions.
This reverts commit d43c092f171e683028e184af56333dab9ce79fcb.
We don't actually need it, init.c is including ppp_opts.h and is doing
the following:
#if !LWIP_ETHERNET && (LWIP_ARP || PPPOE_SUPPORT)
#error "LWIP_ETHERNET needs to be turned on for LWIP_ARP or PPPOE_SUPPORT"
#endif
so the LWIP_ETHERNET fixup is not necessary per se, compatibility with
previously used lwipopts.h files is broken but at least user is warned.
Ethernet support is required for PPPoE but Ethernet support is only set
by default in opt.h if ARP is enabled, which is wrong because the right
condition is ARP and/or PPPoE, unfortunately PPPOE_SUPPORT can't be used
in opt.h because it is not defined if ppp_opts.h is not included before
opt.h in user code.
Fixup the LWIP_ETHERNET configuration value in ppp_opts.h in order to
force Ethernet support if PPPoE is enabled.
Fixes: 3ad2ad2329 ("Remove reference to PPPOE_SUPPORT in opt.h - leads
to compile errors because it has no default definition (only in
ppp_opts.h)"
PPP users can now choose to use an external mbed TLS copy instead of using
our internal old version (but released under a BSDish license) PolarSSL copy.
In order to welcome mbed TLS, we need to ease the switch to:
- embedded PolarSSL 0.10.1-bsd copy
or - external PolarSSL
or - external mbed TLS
This change cleanup all our previously used LWIP_INCLUDED_POLARSSL_* defines,
which were not really useful after all, making them internal build triggers
only, and this change provides a new unique global flag to use an external
PolarSSL copy.
Unfortunately, all functions were renamed when PolarSSL was renamed to
mbed TLS, breaking the API. In order to continue supporting our embedded
PolarSSL copy while allowing our users to use mbed TLS, we need a function
map to deal with the API break.
This commit add a function map for all hashes and ciphers we are currently
using.
